Devices and assumptions
| Device | Qty | Hours a day | Running | Starting | Source |
|---|---|---|---|---|---|
| Phone or laptop charger | 1 | On the whole time | 60 W | No extra | Champion wattage chart |
| Computer monitor (27 in) | 1 | On the whole time | 16.8 W | No extra | ENERGY STAR data |
| Internet router/modem | 1 | On the whole time | 15 W | No extra | Champion wattage chart |
| LED light bulb | 1 | On the whole time | 11.5 W | No extra | Champion wattage chart |
Together: 103 W running, about 103 W while the largest motor starts, and 2,479 Wh a day. Over the 8-hour goal that is 826 Wh at the outlet calculated.
- Everything stays on for the whole outage.
- Laptop charging uses the Champion chart midpoint for a phone or laptop charger; the monitor is the median ENERGY STAR 27-inch display.
- Router and LED bulb use Champion chart midpoints.

What would change this answer
- Your own device watts: the label on the device beats any typical figure. Enter it in the calculator.
- Inverter idle draw: most makers don't publish it, so hours here leave it out. Small loads feel this most.
- Cold: below a maker's temperature range a station may stop discharging or charging.
Our take
A home office is a small load, which makes inverter idle draw matter more than usual: most makers don't publish it, so the hours here lean optimistic. Running the router or laptop from a DC or USB-C port instead of the AC outlet avoids the inverter and stretches the battery.
